[@chnapz]

Hi Doc ! I just wanted to thank you and your wife so much for all your videos which I have looked at over and over before actually believing I could do this. I have just finished my flat re-roofing project here in NB, Canada on a 9 ft x 18ft double sloped flat roof. I bought the GAF liberty cap sheet at home depot. They did not sell the base so I contacted a local commercial roofing supplier and bought some Elastoplex SA Y Polyglass as a base sheet. My challenge was to start on each end of my roof to overlap my way up to the peak to lay my final cap sheet. I also followed your advice and found myself a wonderful wife who helped me carry the rolls up the stairs (I'm a skinny dude lol), I cant carry them by myself. If you want I can share photos of my project to show anybody can do this. I'm a barber and I never thought I would tackle a project like this. Today it's raining, and it' great to see that the drip edge is working, no more leaks. THANK YOU for sharing a thing or two with us, bla bla bla Pat

[@JNCVlogs]

U mind telling me what materials u bought so I can do it to my mobile home too 👍

[@chnapz]

@@JNCVlogs sure :) I used the 2 layer he recommends in the video. Peel and stick base, drip edge, and then Cap sheet made by GAF. Cap sheet was available at Home depot, and the base was available at a local roofing supplies store. My conclusion after one winter : the roof is like now, system works great. The rolls are heavy, I'm a tiny dude and needed help to carry them :) have fun and take your time

[@grominwithrob1339]

That is spot on with the drip edge. I used to do HVAC and we did all our own duct work and plenums. We also made drip edge on our benders for the roofers across the street. We made large flanges so lots of bonding area. The roofers loved it and used it as an demonstration piece when explaining why you should go with their bid. They were not wrong, they were the best because they ALWAYS did it right. More cost effective when you do a good job that generated buisness and never have to deal with the expense of a come back. 👍👍👍👍

[@Chubbycat747]

Thanks for the vids. After owning a home and having leak problems, I've found it interesting ever since (finding/stopping leaks).

[@FlatRoofDoctor]

Thanks Cappy

[@1bottlefed]

Hello all, Just wanted to add my experience on this method. Way before this video back in 1998 I had a leaking built up tar and gravel roof on a slightly pitched addition to my house. I removed the entire old roof back to the rafters and installed sheathing, then I installed a cap a layer of peel and stick roll roofing ( I think it was a GAF product) and then a final layer of sand coated roll roofing. Since it was my own house I followed the instructions carefully and took my time rolling the surface with a 100 lb roller to ensure good adhesion. Well here we are in 2022 and the roof is still in great shape, hardly even find any sand in the gutter when I clean them.

[@victorblock3421]

I'm glad it worked well.

[@wanonalanier2207]

Hi Doc! I just wanted to let you know that I have been watching you and you're precious wife doing these videos, and it gave me the courage to do a flat roof on a sandbag dog househere on my farm. 😊 My dog house is almost finished and I will be putting a rubber flat roof on.

@@JohnSmith-bx5fg it's hilarious. We had a guy in tears when the insurance company came out and found out it was a DIY. Owes 200k in repairs AND got dropped.

No spray primer on the drip edge before the bitumen?

[@ShelleyVideo]

As recently as 10 years ago I would've given this a shot by myself, but at 66, I'll be hiring a pro. The trick is to find a roofer who knows what they're doing and doesn't give you a "taillight warranty"!

[@vanderumd11]

Absolutely. Getting a note outlining warranty is a great piece of mind.

[@justaviewerortwo2924]

Sadly even today a receipt or warranty is meaningless really. Company just goes out of business or changes names. I know a guy who hired a roofer paid this company a crazy amount of money and the roof still leaked.

[@johnp556]

Correction, in 2022 the trick is to find a roofer who will give you an accurate quote. They purposely leave a wood clause in there to replace rotted wood and then hit you in the end with a HUGE additional charge for wood replacement. Careful of this SCAM. He should inspect properly to get a relatively accurate estimate of addional charge and not go over 10% additional to the quote.

[@blackpine6693]

Have to remember contractors have over head…..Liability insurance, WC insurance, truck insurance,payroll,and so on plus they need to make a profit……pay for the boat/vacation home…..yes some go for the throat in this area that’s why one needs to research costs and get several written estimates….the lowest is not always the best….neither is the highest……once work is started …..important the workers know someone is watching…..inspect the work if possible and have the contractor take detailed pictures of the finished job…….never pay the rest owed if the work is not done,or there are issues…..until completed….. Can be done if one has the balls and follows manufacture directions to the T…..and avoids falling off the roof……

[@AJCruzin]

What happens to the high spots on the roof? I ended up with those the last time I did my flat roof with regular roll roofing, and over the years, they dried, cracked, then leaked. I presume the same thing will happen with the stick down roof if it's not perfectly flat?

[@notimportant3686]

by high spots do you mean wrinkles or creases?.... because that shouldn't be, that's poor installation technique.. because those wrinkles are hollow and not adhered to the actual surface which means they will shrink and expand with changing temps and eventually crack

[@DAT-TEXAS-DUDE]

I have a section on my house towards the back that is a 20 x20 flat asphalt shingle roof. Thats the way the house was when we got it anyhow i plan on putting a metal roof over that section for a 2 year temporary fix as it has a couple of small leaks , hoping to save up money to try to remodel that whole section of that roof that leaks and the inside of it also. What are your suggestions as to putting black paper over the shingles and then pearlands before installing the metal roof. Would that help with the leaks to keep it leak free till i gather that money

[@kellycarver2500]

This is a great video, but I am wondering why it looks like he ran the rolls in the wrong direction? Shouldn't the seams be running parallel with the way the water runs? It seems that this way, the water could run up under those seams easier than if it had been laid the other way..?

Hi! Love your videos since I am very new to anything related to roofs (first time home owner). I have a question because I am a bit confused.

My 7 year torch down Bitumen roof garage 20x20 is starting to leak. The "professional" roofer torched granulated Bitumen directly to a tar and gravel roof with the gravel removed. It is a flat roof and there is ponding of water which leads me to suspect why it is failing so soon. I want to fix it so where it will last 20 - 30 years. Should I put a sloped roof on top and then do a 2 ply Bitumen or what other suggestions would you have? Love your videos, thanks.

[@FlatRoofDoctor]

Ok, so torching directly to the existing build-up roof is a no no. The Torch Down will not adhere and start to wrinkle pulling the seams apart. If that is the case, then you need to cut the wrinkles so as to flatten out the surface. I suggest install a new commercial drip edge, over the existing membrane, and then torch directly to the old membrane, after cutting the wrinkles. The use screws with plates to fasten the old membrane properly to the deck Stagger the seams so you are not following the same pattern as the existing. maybe start with a roll cut at 18". No reason to slope the roof in the 1 st explanation. That is the easiest and less expensive way that will last. Only make sure you are melting the 2 layers together very well. That takes extra heat. 1. The other way would be to install tapered ISO insulation. 2. Then self adhering base 3. Commercial drip edge 4. Cap sheet torch granulated send me pics to 203 858 0080 so can give better advice or call

It's OK in a pinch if they need to save for a few months w.e. but in the long run when you keep doing patch work it adds up fast. Then when you do a replacement and have to add in all new wood now cuz the old stuff has rotted away. Your not saving so much anymore. The most recent job I was on had about 12k in wood deck replacement because for about a decade they paid for shoty patchwork that didn't actually get them water tight
